T 0 all wlwm alt may coneern:

Be in known thac I, JACOB H. HOLT, of the eilyot'Monmouth, eounty of Warrenm1d State ot' Illiuo is -lmve iuvented eertain new anti use- 'fl1l lmprovements in Triangulzmr Serapers for leveling and sxnoothiug streets und roa.ds a'nd for removin g snow therefrom, 0f which the followin g is such a full, clear, and exaet description as will enable otl1ers skilled in (alle arl: t0 whieh it; pertains 110 make a.nd use the same, ref'erence being had to theaccompanyingdrawings, in wlxieh similar letters of reference indica.te eorresponding parts in the difl'erent figures.

The objeet of this invenlzion is to produce a maehine whieh shall not only fill the dexnand for suitable road-seraper to be used in grading and leveling, bat shall also be ea.pable of read y oonversion iut0 a snow-plow for the purpose of clearing roads in winter; and the inveutiou consist-s in the construction and arrangement of the difi"erent parts 0f t-he 111aehine in such a warmer that; it may be reversed, as will be hereinafter fully deseribed, and ihen speeifically pointed outin the elaims.

Fignre 1 of the dmwing is a perspective view. Fig. 2 is a. transverse seetion. Fig.3 is a longitudinal seetion.

A A are tl1e side pieces of tl1e machine, and

are iormed of planks of oak or other suilzable wood, about oue foot in Width, eighn feet, or thereabout, in length, and of such thickuess a.s may be needed to give the neeessary strenglah. 'lbe lower half of these side pieees is cove red witl1 a plating of steel er iron, so es to give them a sharp edge and prevent undue wea.r

of the wood. B B is the frame o1" ehe maehine,

eom posed of two parallel pieces, plaeed ab such a distance from each other as to allow the tongue O to enter the space benween them. Attaohed 150 these parallel pieces loy boltsare eross-pieees D D, whieh are, in turn, bolted to the side pieces A A. Suitable braces are also provided,one end being secured 130 the crossto support; all strains to wlxich it n1ay be subjeeted.

'Ihe tongue O is so eonstrueted tlmt it nmy be inserted and seeured between the parallel bars 0f the frame, froxn eitl1er end of tl1e machine, the braces heilig seeured t0 ehe side pieees A A by tl1e szune bolts when the tongue is in either position. This facility of reversal allows the muehine to be applied to a greater rauge 0f purposes Ehen would be possible With bhose in more oommon use.

A drivers seat E, is pl-aced 0ver the center ofthe mael1ine, upon suitable supports attached t0 tl1e parallel lmrs of tl1e machine. 'lhis sea.t is pivoted so that; it ma.y be turned around 150 faee eitl1er way, er is so e0nstrueted without a back as to be used from eit-l1er en d of the maehine.

In using the machine as a snow-plow it moves with its pointed end forward, throwing the s now to eaeh side; but when used for grading er leveling either end may g'o first, es the nature of the work demands.

Having iahus deseribed m y invention, I claim as new, and desire to secure by Letters Patent, the following:

l. 'Ihe reversible tongue C, in eoxnbination With the parallel bars of the frarne B B, as and for the purposes spe0ified.

2. A triangular reversible scraper, provided with a tongueso construeted es to be attached ab eilsher end of l;he seraper, as and for the purposes sei: forth.

In testimony that I elaim the foregoing I hereunto affix my signa.ture this 22(1 day of April, 1876, in the presence of two subseribing witnesses.

JACOB H. HOL'D.
